UNITED STATES PATENT OFFICE.

CORNELIUS CHARLES EDGAR VAN ALSTINE, OF PATERSON, NEW JERSEY, ASSIGNOR OF ONE-HALF TO GEORGE WASHINGTON GRAHAM, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 578,792, dated March 16, 18.97. Application tiled September 12,1896. Serial No. 605,620. (No model.)

To all whom t may concern:

Beit known that I, CORNELIUS CHARLES EDGAR VAN ALSTINE, a citizen of the United States,residing in Paterson county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Thread- Twisters; and I do hereby declare the following to be a full, clear, and exact' description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my present invention is to provide a doubler with means for twisting the threads to furnish a finished product, and thus avoid the necessity of subjecting the threads to the process of throwing, of simple, strong, and durable construction, reliable and efficient in operation.

The invention consists in the improved doubler and its twisting means, and in the combination and arrangement of the various parts thereof, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

In the accompanying drawings, Figure 1 represents an end elevation of a doubler of ordinary construction provided with my improvements, only those parts of the doubler being shown which are necessary to clearly illustrate the nature of my said invention; Fig. 2, an enlarged detail end elevation of the right-hand upper portion of Fig. l; Fig. 3, a detail front elevation of Fig. 2, with certain portions removed and others broken away. Figs. 4 and 5 are a front elevation and top plan View, respectively, of the twister and its supporting reciprocating bar; Fig. 6, an enlarged perspective view of the twister or spinner proper, and Fig. 7 a side elevation thereof.

In said drawings, ct represents the frame, in which are arranged-and on each side of the center thereof-the shafts b and bo, operated in the usual manner, (the driving mechanism therefor not being shown.) On each of said shafts is mounted a pinion b', meshing into gear-wheel b2,which latter is arranged on the shaft c, carrying the cam-wheel c', by

means of which the antifriction-rollers C2 are adapted to be operated. The roller c2 is arranged on the vertical lever c3, fulcrumed at its lower end, as at c4, to the frame of the machine. nected by means of the rod h4 tothe reciprocating bar 71.5; On the shaft bo are mounted at certain intervals a series of friction-wheels d, engaging the friction-rollers d', which are The upper end of said lever is conarranged on a series of short shafts or spin- Y tion-rollers d is arranged a bobbin or spool e of the usual and well-known construction.

On the reciprocating bar h5, which is provided at certain intervals (to correspond to the number of bobbins) with recesses h2o, are secured a series of 'bracket-plates 71.6 by means of the screws 7112 and 71.11, respectively, the latter ones penetrating elongated radial slots hw, arranged in their respective bracket-plates. Each of said bracket-plates h6 is provided with -a central groove or recess hm, in which the grooved pulley 718 is free to revolve, which pulley is mounted on the hollow shaft hl, having its bearings in the said bracket-plate and also in the cover hg of the latter. Said shaft 7i7 penetrates the recess h2o of the reciprocating bar h5 and projects beyond its rear surface.

an endless belt t', passing over the horizontally-arranged grooved pulleys i, operated from the main driving-shaft in any desired manner.

The bracket-plate 71,6 is provided at its slotted end with a notch 7t13, engaged by the flat spring 71,14, which latter tends to force the said plate against the projection h" of the lever tl, pivoted, as at h1, and controlled by the flat spring hw, all as clearly shown in Figs. 4 and 5 of the drawings. `Whenthe pulley hs is to be thrown out of engagement with the endless belt t', the lever 7t15 is pressed backward by the operator, and after the bracket- The pulley lts rests in operative position on IOO plate h6 has been swung upward on the screw h12 (serving as a fulcrum) by theaction of spring h14 the said lever h15 is released, when its projection h17 engages the slot h1@ and thus holds the bracket-plate and the pulley carried thereby out of operative position. i

The hollow shaft h7 and its pulley h8 are provided at one side with the open slots m3 and m2, respectively, of a size large enough to admit the insertion of the threads to be twisted. Said slots are capable of being brought in alinement with the slots m and m11, arranged in and penetrating one side of the bracket-plate h6 and its cover hg, respectively. On the forward end of the shaft hs is arranged a wire forming a loop m, which loop stands substantially in the center line of the hollow shaft and at right angles thereto. On the opposite end of said shaft h8 is also arranged a wire forming a loop m10, which latter is substantially in the center line of Said shaft and in alinement therewith.

By preference the hollow shaft h7 is lined with porcelain or any other suitable material to prevent the threads, while passing through, from becoming bruised or otherwise impaired.

i The threads t t' to be twisted pass from the bobbins u @d (which latter are arranged on the bracket-frame a in the usual manner) over the rod t2, through loop g/, and over rod t3, into and through the loop m, thence through the hollow shaft h7, loop m10, onto the bobbin e. The rods t t' are supported in the bracketframes a3, while the loop g is carried by the spring-wire g, which latter is arranged in such a manner that when the thread passing through its respective loop g' breaks it will drop down upon the lever f and thus throw the latter into engagement with one of the notches of the toothed wheel f and thus stop the rotation of the same and the shaft and bobbin connected therewith.

As the hollow shaft h7, carrying the loop m, (at right angles to the center line of said shaft,) is revolved the threads upon passing through said loop m are twisted together and in that form are wound upon the bobbin. When the twister is to be threaded, the slots m3 and m2 of the shaft h7 and pulley h8 are brought in alinement with the slots m' and m11 of the bracket-plate h6 and hg, respectively, as will be manifest.

I do not intend to limit myself to the precise construction shown and described, as various alterations can be made without changing the scope of my invention; but
